Re: Emacs 26.3 strange ESS init error regarding Projectile and project root.

[Carlo Tambuatco]

I probably will report this issue to them soon. But the strange thing is, 
on my other computer, a Mac, I run emacs 28.0.50, a newer version than 
the emacs 26.3 version I run that is giving me this problem. But I use the 
same version of ESS on 28.0.50, which gives me no problems whatsoever 
on that newer version of emacs.

Something tells me they took ESS in a different direction with no thoughts 
on backwards compatibility. In the meantime, I would like to perhaps down 
grade the ESS version to a version that defininately works on emacs 26.3. 
Is there a way to do that with elpa…?
